3. Spring Boot

3.1 Наследуем наш SpringBootWebJspApplication от SpringBootServletInitializer это позволит нам развертывать наше приложение из классического WAR

package ru.leodev.examples.springboot.springbootwebjsp;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.builder.SpringApplicationBuilder;
import org.springframework.boot.web.support.SpringBootServletInitializer;

@SpringBootApplication
public class SpringBootWebJspApplication extends SpringBootServletInitializer {

	public static void main(String[] args) {
		SpringApplication.run(SpringBootWebJspApplication.class, args);
	}

	@Override
	protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {
		return application.sources(SpringBootWebJspApplication.class);
	}
}

package ru.leodev.examples.springboot.springbootwebjsp;

import org.springframework.boot.SpringApplication;

import org.springframework.boot.autoconfigure.SpringBootApplication;

import org.springframework.boot.builder.SpringApplicationBuilder;

import org.springframework.boot.web.support.SpringBootServletInitializer;

@SpringBootApplication

public class SpringBootWebJspApplication extends SpringBootServletInitializer {

public static void main(String[] args) {

SpringApplication.run(SpringBootWebJspApplication.class, args);

}

@Override

protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {

return application.sources(SpringBootWebJspApplication.class);

}

[stextbox id=’alert’]Как я уже писал в комментариях pom.xml, из под Intellij IDEA после этого шага мне не удалось запустить проект, причину так и не нашел. Но из консоли сервер стартует без проблем используя команды:[/stextbox]

mvn clean package
mvn spring-boot:run

1 2	mvn clean package mvn spring-boot:run

3.2 Добавляем простой spring контроллер

package ru.leodev.examples.springboot.springbootwebjsp.controller;

import org.springframework.beans.factory.annotation.Value;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;

import java.util.Map;

@Controller
public class MainController {
    // внедряем значение из application.properties
    @Value("${welcome.message:test}")
    private String message = "Hello World";

    // Обычно я использую интерфейс Model, но в целом разницы нет,
    // т.к. используется реализация LinkedHashMap(Key, Val)
    @RequestMapping("/")
    public String welcome(Map<String, Object> model) {
        model.put("message", this.message);
        return "index";
    }
}

package ru.leodev.examples.springboot.springbootwebjsp.controller;

import org.springframework.beans.factory.annotation.Value;

import org.springframework.stereotype.Controller;

import org.springframework.web.bind.annotation.RequestMapping;

import java.util.Map;

@Controller

public class MainController {

// внедряем значение из application.properties

@Value("${welcome.message:test}")

private String message = "Hello World";

// Обычно я использую интерфейс Model, но в целом разницы нет,

// т.к. используется реализация LinkedHashMap(Key, Val)

@RequestMapping("/")

public String welcome(Map<String, Object> model) {

model.put("message", this.message);

return "index";

}

4. JSP + Resources + статические файлы

4.1 Для файлов JSP, создаем каталог src/main/webapp/WEB-INF/jsp/

<!DOCTYPE html>
<%@ taglib prefix="spring" uri="http://www.springframework.org/tags"%>
<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core"%>
<%@ page contentType="text/html; charset=UTF-8" %>
<html lang="en">
<head>
    <!-- Подключаем bootstrap CSS,
        Spring boot автоматически замапит ресурс благодаря зависимости webjars в pom.xml -->
    <link rel="stylesheet" type="text/css" href="webjars/bootstrap/3.3.7/css/bootstrap.min.css" />
    <!--
	<spring:url value="/css/main.css" var="springCss" />
	<link href="${springCss}" rel="stylesheet" />
	 -->
    <c:url value="/css/main.css" var="jstlCss" />
    <link href="${jstlCss}" rel="stylesheet" />
</head>
<body>

<nav class="navbar navbar-inverse">
    <div class="container">
        <div class="navbar-header">
            <a class="navbar-brand" href="#">Spring Boot JSP</a>
        </div>
        <div id="navbar" class="collapse navbar-collapse">
            <ul class="nav navbar-nav">
                <li class="active"><a href="#">Главная</a></li>
                <li><a href="#about">Обо мне</a></li>
            </ul>
        </div>
    </div>
</nav>

<div class="container">

    <div class="starter-template">
        <h1>Пример Spring Boot Web JSP</h1>
        <h2>Сообщение: ${message}</h2>
    </div>

</div>
<script type="text/javascript" src="webjars/bootstrap/3.3.7/js/bootstrap.min.js"></script>
</body>
</html>

<!DOCTYPE html>

<%@ taglib prefix="spring" uri="http://www.springframework.org/tags"%>

<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core"%>

<%@ page contentType="text/html; charset=UTF-8" %>

<head>

<!-- Подключаем bootstrap CSS,

Spring boot автоматически замапит ресурс благодаря зависимости webjars в pom.xml -->

<!--

<spring:url value="/css/main.css" var="springCss" />

-->

<c:url value="/css/main.css" var="jstlCss" />

</head>

<body>

<a class="navbar-brand" href="#">Spring Boot JSP</a>

</div>

<li class="active"><a href="#">Главная</a></li>

</ul>

</div>

</nav>

<h1>Пример Spring Boot Web JSP</h1>

<h2>Сообщение: ${message}</h2>

</div>

</body>

</html>

4.2 Статические файлы, такие как стили CSS или Javascript кладем в /src/main/resources/static/

Соответственно в static создаем каталог css и в него кладем тестовый main.css

h1{
    color: #3858ff;
}

h2{
    color: #ff801b;
}

h1{

color: #3858ff;

}

h2{

color: #ff801b;

}

4.3 Все properties файлы хранятся в корне директории ресурсов: /src/main/resources/

в моем случае spring сгенерировал его при создании проекта, поэтому мы лишь прописываем параметр для Внедрения зависимости(DI)

spring.mvc.view.prefix: /WEB-INF/jsp/
spring.mvc.view.suffix: .jsp

welcome.message: Hello Leodev!

spring.mvc.view.prefix: /WEB-INF/jsp/

spring.mvc.view.suffix: .jsp

welcome.message: Hello Leodev!

[stextbox id=’alert’ caption=’Ограничения JSP’]Вы не можете создать исполняемую jar для запуска встроенного веб-сервера Tomcat + JSP из-за жестко закодированного шаблона файла в Tomcat. Подробности тут Spring Boot – JSP limitation.[/stextbox]

Исходники: spring-boot-web-jsp

1. Структура каталогов

2. Зависимости

3. Spring Boot

4. JSP + Resources + статические файлы

5. Запуск приложения
